This paper presents a new high speed positioning servomechanism in order to machine an article with a non-circular profile. In the non-circular machining by a lathe, the positioning servomechanism of a cutting tool is necessary, and, in order to operate it with high efficiency, this positioning servomechanism must have the enough force to overwhelm cutting resistance and have a good responsiveness. Previously an electrohydraulic servomechanism was applied to the cutting tool positioning

And so a new high speed and high power positioning servomechanism was developed. This new servomechanism is actuated by electromagnetic attractive force in the same as a support mechanism by an active magnetic bearing. Usual mechanical springs were incorporated into the fundamental servomechanism by the electromagnetic attractive force to achieve the high responsiveness on the lower electric power, and the new servomechanism was developed to make the high responsiveness on practical electric power possible.
